Cai Ming's father published an article with 100,000 words. The remuneration was 100 yuan per 1,000 words. According to the regulations, if the remuneration exceeded 800 yuan, 10% of the individual income tax should be paid. Therefore, Cai Ming's father had to multiply the 100 yuan per thousand words by 10% and add 800 yuan to get the total fee. After that, he would divide the total payment by 10000 to get the 1,000-word payment and pay personal income tax according to the relevant regulations. To be specific, Cai Ming's father needed to first calculate the total remuneration, which was 100,000 words, multiplied by 10000 yuan, which was 1 million yuan. Then, he divided the total fee by 10000 to get 10000 yuan per thousand words. Finally, according to the relevant regulations, the total remuneration minus 800 yuan, multiplied by 10%, plus 800 yuan was the personal income tax that needed to be paid. Cai Ming's father needed to submit the calculated royalties and personal income tax information to the relevant agencies and pay according to the regulations in order to enjoy the corresponding royalties.
